LMS202E

15KV ESD Rated, 5V Single Supply TIA/EIA-232 Dual

Transceivers

General Description

The LMS202E features two transmitters and two receivers

for RS-232 communication. It has a DC-to-DC converter that

permits the device to operate with only a single +5V power

supply. The on-chip DC-to-DC converter which utilizes four

external 0.1µF capacitors to generate dual internal power

supplies for RS-232 compatible output levels.

The device meet EIA/TIA-232E and CCITT V.28 specifica-

tions up to 230kbits/sec. The LMS202E is available in a 16

pin narrow and wide SOIC package.

The transmitter outputs and receiver inputs have

electrostatic discharge (ESD) protection. The LMS202E sur-

vives a

pins when subjected according to Human Body Model or IEC

1000-4-2 (EN61000-4-2),air-gap specification. It survives a

4-2), contact specification. This device is designed for use in

harsh environments where ESD is a concern.
